Changing the Behavior of Parametric Resonance in Mems Oscillators by Tuning the Effective Cubic Stiffness
نویسندگان
چکیده
Nonlinearity plays a critical role on the behavior of oscillators operating in the parametric resonance mode. Here, we study the effects of Effective Nonlinear Parameter, (effective cubic stiffness), γ3eff, on the behavior of parametric resonance in a micro electro mechanical oscillator. The value of γ3eff can be tuned by changing the amplitude of applied voltage. Varying the sign of γ3eff can switch bi-stable area from one side of the parametric resonance area to the other side. Both experiment and analysis show this switch and the results agree very well with each other.

Effect of cubic nonlinearity on auto-parametrically amplified resonant MEMS mass sensor
Parametric resonance has been well established in many areas of science, including the stability of ships, the forced motion of a swing and Faraday surface wave patterns on water. We have previously investigated a linear parametrically driven torsional oscillator and along with other groups have mentioned applications including mass sensing, parametric amplification, and others. Here, we thorou...

This paper presents a novel RF MEMS (Micro Electromechanical System) fixed-fixed switch for very fast switching. Using the obtained equations, the switching time depends on the stiffness and effective mass of the switch beam so that the switching time will be decreased by higher stiffness (spring constant) and lower effective mass. In new design, the suspension bridge is a three-layer beam so t...

Micro/nanocantilevers have been employed as sensors in many applications including chemical and biosensing. Due to their high sensitivity and potential for scalability, miniature sensing systems are in wide use and will likely become more prevalent in micro/nano-electromechanical systems (M-NEMSs). This paper is mainly focused on the use of sensing systems that employ micro/nano-size cantilever...
متن کاملPhase Measurements of Non - Linear Response in Mems Oscillators
We have fabricated several varieties of micro and nanomechanical resonators and have studied their phase response when driven at their natural frequency with and without parametric pumping. We found that micron-sized paddle oscillators with submicron-sized supports had resonant frequencies in the 3-10 MHz range for their translational mode. Due to the stretching of the support beams, the effect...
